Hi guys. I have had the 510 kit since last week and have run into a possible problem. I do not vape constantly or anything (probably one to two puffs per hour- if that). But last night, after charging up my auto battery, I put the atomizer and cart on, and...nothing. Not even a smidge of vapor. I noticed that the led wasnt functioning either. I tried attaching my other atty, and even a different cart...nothing. If I wave the battery back and forth with nothing attached, it sometimes lights up on the LED, but no vapor or hit is produced. I have not dropped it, no juice leaked in it, and always keep it in a cool dry place. I have heard of batteries not lasting very long, but less than 2 weeks? This is ridiculous. Now, my manual battery works perfect, and I probably use it twice as much than I do the auto. Can someone please help?
